Answer 1

那是因为那个文件configure.py没有setup.py.configure.py生成一个make文件,用于通过将--qmake选项传递给configure.py来针对您选择的qt库构建pyqt,它也有不同的选项.我建议用pip维护者填写一个bug.

Answer 2

如果你在Mac上,你可以使用自制软件:

brew install pyqt

Answer 3

或者，您可以使用ActivePython的二进制包管理器安装 PyQt4 。

$ pypm install pyqt4
The following packages will be installed into "~/.local" (2.7):
 pyqt4-4.8.3.0
Hit: [pypm-free.activestate.com] pyqt4 4.8.3.0
Installing pyqt4-4.8.3.0
$

只要你已经有了PyPM，就不需要编译。
